Description

Technical Field

[0001] This invention relates to the field of metallurgical waste treatment technology, specifically to a collection and treatment device for metallurgical engineering waste. Background Technology

[0002] Metallurgical waste refers to solid and semi-solid waste generated throughout the entire metallurgical production process (mining, beneficiation, sintering, smelting, refining, and rolling). Based on its source and form, it can be divided into three main categories: metallic waste, non-metallic waste, and hazardous waste. Most of these categories require standardized disposal through specialized collection and treatment equipment due to resource waste, environmental pollution, and safety hazards. Metallic waste, containing valuable metals and possessing high recycling value, is one of the core targets for collection and treatment.

[0003] Existing metallurgical waste treatment equipment is mostly single-function designed, typically handling only one type of waste. It requires multiple decentralized units to complete pretreatment, crushing, separation, and briquetting processes, resulting in large footprints, high investment costs, and the need for manual labor or additional conveying equipment for material transfer between different stages. This leads to a disjointed overall processing flow and low efficiency. Furthermore, existing equipment has a low rate of waste heat recovery from high-temperature molten smelting slag, resulting in significant heat loss and energy waste. During waste briquetting, air and moisture trapped between material particles can lead to insufficient density in the finished briquettes, affecting subsequent recycling. Additionally, there is a lack of flexible disposal methods for slag of different particle sizes after treatment, making it difficult to simultaneously meet the dual needs of direct application and briquetting, further limiting the economic viability and applicability of metallurgical waste treatment. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this invention provides a collection and processing device for metallurgical engineering waste. By integrating multiple functional units such as feeding, pretreatment, crushing, separation, briquetting, and discharging, different types of waste such as high-temperature molten smelting slag and metal-containing scrap can be processed in the same device, eliminating the need for multiple separate devices, thus significantly reducing the equipment footprint and investment costs.

[0016] By incorporating a heat exchange structure in the high-temperature waste treatment process, the residual heat in the high-temperature molten slag can be effectively recovered and used for material drying and preheating before briquetting, avoiding direct energy loss and reducing overall energy consumption. At the same time, through structural designs such as screening and cyclone separation, coarse materials, fine materials, and metal components in the waste can be effectively separated, allowing waste of different components to be recycled or disposed of in a targeted manner, reducing resource waste. Furthermore, the fully enclosed treatment and storage structure can effectively avoid environmental problems such as dust and wastewater discharge, meeting environmental protection requirements.

[0017] By designing a flexible coarse material handling structure, the coarse material can be applied directly or briquetteed for storage according to actual needs, adapting to different downstream utilization scenarios. The introduction of vacuum treatment and waste heat preheating in the briquetting process can effectively remove air and moisture from the material, improve the density and stability of the briquette product, and facilitate subsequent transportation and palletizing. At the same time, all units of the equipment adopt automated control and linkage design, which can flexibly adjust the operating status according to the type of waste and processing requirements, reduce the intensity of manual operation, and improve the stability and reliability of equipment operation.

[0022] Example 1

[0023] Please see Figures 1 to 8 As shown, a collection and processing device for metallurgical engineering waste includes: Waste processing box 1 and waste briquetting box 2 are fixedly installed on both sides of the top of the base, and a guide frame 3 is fixedly installed between waste processing box 1 and waste briquetting box 2. The interior of waste briquetting box 2 is equipped with a waste collection and briquetting unit. The interior of waste processing box 1 and waste briquetting box 2 are connected by the guide frame 3 to realize the automatic briquetting and collection of processed metallurgical engineering waste.

[0024] Waste processing tank 4 is fixedly installed on top of waste processing box 1, and a fixing frame 5 is fixedly installed inside the waste processing tank 4. A feed inlet 6 is fixedly installed on one side of the fixing frame 5, and a feed inlet 7 is fixedly installed in the middle of one side of the waste processing box 1. High-temperature molten smelting slag is fed into the waste processing tank 4 and the fixing frame 5 through feed inlet 6 for pre-briquetting treatment. Metal-containing scraps are fed into the interior of the waste processing box 1 through feed inlet 7 for pre-briquetting treatment. Finally, the pre-treated waste is sent into the interior of the waste briquetting box 2 for briquetting and storage. Through the integrated setting of the processing equipment, not only is the floor space of the equipment reduced, but also the simultaneous processing of different types of waste is achieved, effectively improving the collection and processing efficiency of metallurgical engineering waste.

[0025] A hydrocyclone 12 is fixedly installed on the back of the waste treatment box 1. A high-temperature waste treatment unit is installed inside the fixing frame 5, and the high-temperature waste treatment unit is connected to the feed end of the hydrocyclone 12. A metal-containing waste crushing unit is installed at the bottom inside the waste treatment box 1, and the metal-containing waste crushing unit is connected to the discharge end of the hydrocyclone 12. After the high-temperature molten slag is heat-exchanged, water-quenched and screened by the high-temperature waste treatment unit, the mixture of fine material and water after the high-temperature molten slag treatment is sent into the interior of the hydrocyclone 12. The fine material and water are separated inside the hydrocyclone 12. The separated fine material enters the metal-containing waste crushing unit.

[0026] Regarding the structural design in the above embodiments, it should be further explained that by integrating the waste processing box 1, the waste briquetting box 2, and the guide frame 3 on the top of the base, and setting the waste processing tank 4 and the fixing frame 5 on the top of the waste processing box 1, the simultaneous processing of high-temperature molten smelting slag and metal-containing scrap is achieved; the material separation design of the feed inlet 1 6 and the feed inlet 2 7, combined with the separation function of the hydrocyclone 12 for fine materials and water, allows different types of waste to complete the entire process of pretreatment, conveying and briquetting in the same equipment, which not only avoids the land occupation problem of multiple dispersed equipment, but also reduces the manual transfer link through the connection design of the guide frame 3, improving the continuity and efficiency of the overall collection and processing; at the same time, the connection between the high-temperature waste processing unit and the metal-containing waste crushing unit allows the fine materials after the high-temperature molten slag treatment to directly enter the crushing chamber 25 to mix with the metal scrap, realizing the co-processing of waste and reducing resource waste.

[0027] Example 2

[0028] Specifically, such as Figure 2As shown, a discharge rack 8 is fixedly installed on one side of the waste processing box 1, and a discharge port 9 is provided on one side of the discharge rack 8. The discharge port 9 is controlled to open and close by a movable discharge sealing plate. When the coarse material after high-temperature molten slag treatment is used directly, the coarse material after high-temperature molten slag treatment sent out from the discharge rack 8 is discharged after the discharge sealing plate is opened, and the coarse material is collected directly. A guide rack 2 10 is also fixedly installed at the bottom of the discharge rack 8, and the bottom of the guide rack 2 10 extends into the interior of the guide rack 3. When the coarse material after high-temperature molten slag treatment is collected, the coarse material after high-temperature molten slag treatment inside the discharge rack 18 is guided into the interior of the guide rack 3 through the guide rack 2 10, and then the coarse material after high-temperature molten slag treatment is sent into the interior of the waste briquetting box 2 for briquetting and collection by the waste collection and briquetting unit.

[0029] As a further explanation of the solution in the embodiments of the present invention, such as Figures 2 to 5 As shown, the high-temperature waste treatment unit includes a spiral guide frame 13, a jacketed heat exchange frame 14, and a mounting frame 15. The spiral guide frame 13 is fixedly installed inside the mounting frame 5, and the inside of the feed inlet 6 is connected to the inside of the spiral guide frame 13. The jacketed heat exchange frame 14 is fixedly installed in the middle of the waste treatment tank 4, and the top of the jacketed heat exchange frame 14 is connected to the bottom of the spiral guide frame 13. The mounting frame 15 is fixedly installed at the bottom of the jacketed heat exchange frame 14, and a discharge port is also provided in the middle of the bottom of the jacketed heat exchange frame 14. Several high-pressure nozzles 16 are rotatably installed inside the mounting frame 15, and one side of each of the several high-pressure nozzles 16 is fed by a micro motor installed inside the mounting frame 15. The rotation drive allows for flexible adjustment of the spray angle of the high-pressure nozzles 16. Several high-pressure nozzles 16 are arranged at equal angles about the central axis of the mounting frame 15, and the spray ports of several high-pressure nozzles 16 all face the discharge port at the bottom of the jacketed heat exchange frame 14. A conical guide frame 18 is fixedly provided at the bottom of the mounting frame 15, and several guide grooves are provided between the bottom of the mounting frame 15 and the top of the conical guide frame 18. A conical guide frame 17 is fixedly provided on the outer side of the bottom of the jacketed heat exchange frame 14, and a spiral guide frame 19 is fixedly provided between the inner wall of the conical guide frame 17 and the outer circumferential surface of the conical guide frame 18. The bottom of the conical guide frame 17 extends into the interior of the waste treatment box 1.

[0030] Furthermore, a cooling water delivery pipe is fixedly installed on one side inside the mounting frame 5, and one end of the cooling water delivery pipe extends into the interior of the mounting frame 15. The interior of the cooling water delivery pipe is connected to the interior of several high-pressure nozzles 16. Cooling water is delivered into the interior of several high-pressure nozzles 16 through the cooling water delivery pipe, and the cooling water is sprayed onto the high-temperature molten slag material by several high-pressure nozzles 16 for water quenching and granulation treatment.

[0031] Specifically, the high-temperature molten slag is fed into the interior of the fixed frame 5 through the feed port 6. Inside the fixed frame 5, the high-temperature molten slag flows downward along the spiral guide frame 13. The high-temperature molten slag enters the interior of the jacketed heat exchange frame 14 from the spiral guide frame 13 and finally flows out through the discharge port at the bottom center of the jacketed heat exchange frame 14. During the outflow of the high-temperature molten slag, a high-speed fan-shaped water curtain is sprayed onto the high-temperature molten slag through several high-pressure nozzles 16 inside the mounting frame 15, breaking the high-temperature molten slag into fine droplets. The droplets come into full contact with the cooling water inside the conical guide frame 17 and are instantly cooled to below 100 degrees Celsius, forming glassy granular slag. The spiral guide frame 19 is used to extend the slag-water mixing time to ensure granulation uniformity.

[0032] As a further explanation of the embodiment of the present invention, in order to effectively utilize the heat in the high-temperature molten slag, the spiral guide frame 13 and the jacketed heat exchange frame 14 are provided with interconnected heat exchange channels. The liquid inlet of the heat exchange channel is located at the upper end of the spiral guide frame 13, and the spiral guide frame 13 is provided with a matching spiral hollow heat exchange channel. When the high-temperature molten slag flows on the spiral guide frame 13, the heat exchange medium in the heat exchange channel can fully replace the heat of the high-temperature molten slag. The heat exchange channel inside the jacketed heat exchange frame 14 is located in the jacket layer, and the liquid inlet of the jacket layer is connected to the inside of the spiral guide frame 13. The bottom end of the heat exchange channel is connected; a circulating heat exchange tube 20 is fixedly installed on one side inside the jacketed heat exchange frame 14 and on one side at the top of the spiral guide frame 13, and one end of each of the two circulating heat exchange tubes 20 extends into the interior of the waste briquetting box 2; the two circulating heat exchange tubes 20 realize the circulation of the heat exchange medium in the heat exchange channel inside the spiral guide frame 13 and the jacketed heat exchange frame 14, thereby realizing the continuous heat replacement treatment of the high-temperature molten slag; a circulating liquid pump is provided at one end of the circulating heat exchange tube 20 connected to the interior of the spiral guide frame 13, and the circulating liquid pump controls the circulation of the heat exchange medium in the two circulating heat exchange tubes 20.

[0033] Specifically, such as Figure 5As shown, a vibrating screen 21 is installed at the top inside the waste treatment box 1, and the bottom of the vibrating screen 21 generates vibration force through a vibrating motor. A pusher plate 22 is also movably installed on one side inside the waste treatment box 1, and the pusher plate 22 is driven by a servo electric cylinder fixed on one side of the waste treatment box 1. The pusher plate 22 and the discharge rack 8 are both located on the upper end face of the vibrating screen 21, and the inner diameters of the pusher plate 22 and the discharge rack 8 are matched. The discharge rack 8 is equipped with an electromagnetic control valve. After the coarse and fine materials of the high-temperature molten slag granulated by the vibrating screen 21 are separated, the coarse material remains above the vibrating screen 21. The servo electric cylinder drives the pusher plate 22 to push the coarse material above the vibrating screen 21 into the discharge rack 8. After the electromagnetic control valve inside the discharge rack 8 is opened, the coarse material of the high-temperature molten slag granulated into the discharge rack 8, realizing the collection of the coarse material of the high-temperature molten slag granulated into the discharge rack 8.

[0034] Furthermore, the bottom of the vibrating screen 21 is also fixedly provided with an upper feeding frame 23, and one end of the upper feeding frame 23 is connected to the inside of the feed inlet of the hydrocyclone 12; the mixture of fine material and cooling water after screening enters the inside of the hydrocyclone 12 through the upper feeding frame 23, and the hydrocyclone 12 is used to separate the fine material and cooling water; the separated fine material then enters the lower part of the waste treatment box 1 for further collection and processing.

[0035] Regarding the structural design in the above embodiments, it should be further explained that the heat exchange channel connecting the spiral guide frame 13 and the jacketed heat exchange frame 14, in conjunction with the circulating heat exchange tube 20, transports the heat of the high-temperature molten slag to the spiral heat conduction groove 35 of the waste briquetting box 2, realizing the recovery and utilization of waste heat. This allows for preheating and drying of the waste material before briquetting without the need for an additional heat source. The spiral hollow structure of the spiral guide frame 13 extends the flow path of the slag, allowing the heat exchange medium to fully displace heat. Furthermore, on the mounting bracket 15 at the bottom of the jacketed heat exchange frame 14, several adjustable-angle high-pressure nozzles 16 form a fully covered high-speed water curtain, breaking the molten slag into uniform particles. The fine droplets, the conical guide frame 17 and the spiral guide frame 2 19 further extend the slag-water mixing time, ensuring uniform particle size of the granulated slag; the vibrating screen 21, together with the pusher plate 1 22 and the discharge frame 1 8 and guide frame 2 10, realizes the dual-mode switching of direct discharge / briquette collection of coarse material, which not only meets the need for coarse slag to be used directly as building material, but also allows the coarse material to be introduced into the briquette box through the guide frame 2 10, improving the adaptability of the equipment; the connection between the hydrocyclone 12 and the upper feeding frame 23 allows the mixture of fine material and water to be efficiently separated, and the separated fine material enters the crushing chamber 25 to recover associated metals, and water resources can also be recycled, reducing secondary pollution.

[0036] Example 3

[0037] Specifically, such as Figure 4 and Figure 5 As shown, the metal-containing waste crushing unit includes crushing rollers 26. A crushing chamber 25 is located at the bottom inside the waste processing box 1. A lower feeding frame 24 is fixedly connected to the discharge port of the hydrocyclone 12, and the bottom of the lower feeding frame 24 communicates with the interior of the crushing chamber 25. Two crushing rollers 26 are rotatably arranged above the interior of the crushing chamber 25, and the two crushing rollers 26 rotate relative to each other. Specifically, a guide slope is provided at the top of the crushing chamber 25, and the interior of the second feed inlet 7 communicates with the guide slope. Metal-containing waste is conveyed through the second feed inlet 7 to the space between the two crushing rollers 26, utilizing the two relatively rotating crushing rollers. Roller 26 crushes the metal-containing waste. A crushing servo motor is provided on the front of the waste processing box 1. The output shaft of the crushing servo motor drives one of the crushing rollers 26 to rotate. At the same time, one end of each of the two crushing rollers 26 is fixed with a transmission gear that meshes with each other. Therefore, when one of the crushing rollers 26 rotates, the two crushing rollers 26 rotate relative to each other through the two meshing transmission gears, crushing the metal-containing waste. The crushed metal-containing waste falls into the lower part of the crushing chamber 25. At the same time, the screened fine material is fed into the lower part of the crushing chamber 25 through the lower feeder 24.

[0038] Furthermore, a pusher plate 27 is movably installed on one side of the crushing chamber 25, and the pusher plate 27 is matched with the inner diameter of the guide frame 3. One side of the pusher plate 27 is driven by a servo cylinder installed on one side of the waste processing box 1. Electromagnetic control valves are installed on both sides of the guide frame 3. The servo cylinder pushes the pusher plate 27 to one side of the waste briquetting box 2. The pusher plate 27 pushes the crushed material and fine material below the crushing chamber 25 into the waste briquetting box 2 through the guide frame 3 for collection and briquetting. In addition, after the coarse material is fed into the guide frame 3, the pusher plate 27 pushes the coarse material inside the guide frame 3 into the waste briquetting box 2 for collection and briquetting.

[0039] As a further embodiment of the present invention, the waste collection and briquetting unit includes a briquetting plate 34, and a vacuum pump 28 is fixedly installed on the top of the waste briquetting box 2, and the output end of the vacuum pump 28 is connected to the interior of the waste briquetting box 2; by using the vacuum pump 28 to perform vacuum treatment on the interior of the waste briquetting box 2, the waste collection and briquetting is in a vacuum environment, the air between the waste particles is pre-extracted, the particles can fill the gaps more tightly during briquetting, the briquetting density can be greatly improved, and there is no need to increase the briquetting pressure.

[0040] Furthermore, a fixing plate 30 is fixedly installed at the top inside the waste briquetting box 2, and a briquetting plate 34 is movably installed below the fixing plate 30. A briquetting servo cylinder 29 is fixedly installed at the top of the waste briquetting box 2, and the bottom end of the drive shaft of the briquetting servo cylinder 29 is fixedly connected to the top of the briquetting plate 34. The briquetting plate 34 is controlled to move downward by the drive end of the briquetting servo cylinder 29, and the briquetting plate 34 is used to briquetize and collect the waste particles inside the waste briquetting box 2.

[0041] Furthermore, two adjusting screws 31 are rotatably provided inside the waste briquetting box 2 and above the fixed plate 30. Briquetting limiting plates 32 are slidably provided on both the front and rear sides of the waste briquetting box 2, and the tops of the two briquetting limiting plates 32 are threadedly connected to the surfaces of the two adjusting screws 31 respectively. The tops of both briquetting limiting plates 32 penetrate the interior of the fixed plate 30 and extend above it. The front and rear sides of the fixed plate 30 are provided with sliding grooves that mate with the briquetting limiting plates 32, and the inner...

The two adjusting screws 31 are synchronously driven by a synchronous belt. The front and rear sides of the surface of the adjusting screw 31 are provided with external threads with opposite directions of rotation, so that when the adjusting screw 31 rotates, the two briquetting limit plates 32 are displaced in relative or opposite directions.

[0042] Furthermore, a movable sealing frame 36 is movably provided inside the waste briquetting box 2 on the side near the first guide frame 3. The movable sealing frame 36 moves up and down by a built-in electric push rod, thereby sealing the side of the waste briquetting box 2 near the first guide frame 3. A second discharge frame 11 is movably provided inside the waste briquetting box 2, and an electromagnet is fixedly provided on the inner side of the second discharge frame 11. A discharge servo cylinder 33 is fixedly provided on one side of each of the two briquetting limit plates 32, and a magnetic adsorption block is fixedly provided at the driving end of each of the two discharge servo cylinders 33. A spiral heat conduction groove 35 is also provided at the bottom inside the waste briquetting box 2, and the two ends of the spiral heat conduction groove 35 are respectively connected to the bottom ends of the two circulating heat exchange tubes 20.

[0043] It should be noted that by adjusting the drive end of the screw 31, the two pressing limit plates 32 are controlled to move relative to each other, gathering the waste particles inside the waste briquetting box 2 in the middle. The heat exchange medium flowing inside the spiral heat-conducting groove 35 dries the waste particles. Then, a vacuum is applied to the inside of the waste briquetting box 2. Small vacuum holes are provided at the top inside the pressing limit plates 32. Finally, the drive end of the pressing servo cylinder 29 controls the pressing plate 34 to move downwards, pressing the waste particles into blocks to obtain blocky metallurgical engineering waste, which is then discharged. The electromagnet on one side of the second frame 11 attracts the blocky metallurgical engineering waste, releasing the vacuum environment inside the waste briquetting box 2. The discharge servo cylinder 33 on one side of the two briquetting limit plates 32 is connected to the discharge frame 11. The discharge frame 11 is pushed outward by the drive end of the two discharge servo cylinders 33. The discharge frame 11 drives the blocky metallurgical engineering waste inside the waste briquetting box 2 to slide out, completing the briquetting, collection and discharge operation of the metallurgical engineering waste. By stacking the blocky metallurgical engineering waste, the storage space of the metallurgical engineering waste is effectively reduced.

[0044] Regarding the structural design in the above embodiments, it should be further explained that the metal-containing scrap is crushed by two relatively rotating crushing rollers 26. Combined with the guide slope and lower feeding frame 24, the crushed scrap and high-temperature slag fines are mixed in the crushing chamber 25. The pusher plate 27 smoothly pushes the mixture into the guide frame 3, ensuring the continuity of material conveying. In the waste material collection and briquetting unit, the vacuum pump 28 evacuates the inside of the waste briquetting box 2, pre-extracting air from between the material particles. Combined with the pressurizing action of the briquetting plate 34, this makes the briquetting particles more tightly packed, improving the density of the block. The adjusting screw 31 drives... The relative movement of the two pressing limit plates 32 can gather the material in the middle, and the residual heat medium in the spiral heat conduction groove 35 can dry the material, reducing the porosity and delamination defects after pressing. The closed design of the movable closed frame 36 ensures the stability of the vacuum environment, while the electromagnet adsorption of the discharge rack 11 and the pushing structure of the discharge servo cylinder 33 realize the safe discharge of the finished pressed briquettes and avoid the material scattering after the vacuum is released. The overall structure improves the quality of pressed briquettes and storage efficiency through the synergy of residual heat preheating, vacuum pressing and automatic discharge. The waste blocks after pressing are also easy to stack and store, which greatly reduces the storage space.

[0045] Example 4

[0046] Specifically, this embodiment discloses a working method for a collection and processing device for metallurgical engineering waste, applied to the collection and processing device for metallurgical engineering waste proposed in the above embodiment, comprising the following steps: Step 1: Sorting and Preheating Heat Exchange: High-temperature molten slag is fed into the spiral guide frame 13 inside the fixed frame 5 through feed port 6. As the slag slowly falls along the spiral path, the medium in the heat exchange channel inside the spiral guide frame 13 and the jacketed heat exchange frame 14 absorbs the heat of the slag and is transported to the spiral heat conduction groove 35 at the bottom of the waste briquetting box 2 through the circulating heat exchange pipe 20. At the same time, metal-containing scraps are fed into the guide slope inside the waste processing box 1 through feed port 7, ready to enter the crushing stage.

[0047] Step 2, High-Temperature Slag Quenching Granulation and Screening: The high-temperature molten slag flows from the spiral guide frame 13 into the jacket heat exchange frame 14, and then flows out through the bottom outlet. Several high-pressure nozzles 16 on the mounting frame 15 spray out a high-speed fan-shaped water curtain to break it into fine droplets. The droplets are fully mixed and cooled with cooling water in the conical guide frame 17 and the spiral guide frame 19, forming granular slag material, which then falls into the vibrating screen 21. After screening by the vibrating screen 21, the coarse material remains on the screen surface and is pushed to the discharge frame 8 by the pusher plate 22. It can be directly discharged or introduced into the guide frame 3 via the guide frame 20. The mixture of fine material and water is sent into the hydrocyclone 12 via the upper feeding frame 23.

[0048] Step 3, material crushing and mixing conveying: The fine material separated by the hydrocyclone 12 enters the crushing chamber 25 through the lower feeder 24. At the same time, the metal fragments are crushed by two relatively rotating crushing rollers 26 and fall into the bottom of the crushing chamber 25. The pusher plate 27 pushes the mixed material into the guide frame 3. If it is necessary to press the coarse material to collect it, the coarse material also enters the guide frame 3 through the guide frame 2 10 and is conveyed together to the waste briquetting box 2.

[0049] Step 4, Vacuum briquetting: The movable closed frame 36 closes the feed side of the waste briquetting box 2, the vacuum pump 28 evacuates the box, the adjusting screw 31 drives the two briquetting limit plates 32 to move relative to each other and gather the material, and the residual heat medium in the spiral heat conduction groove 35 dries and preheats the material; then the briquetting servo electric cylinder 29 drives the briquetting plate 34 to move downward, and the material is pressed into a dense block in a vacuum environment.

[0050] Step 5, Finished Product Discharge and Storage: After the briquetting is completed, the vacuum environment is released, the electromagnet in the discharge rack 2 11 attracts the block, and the two discharge servo cylinders 33 drive the discharge rack 2 11 to push it outward, causing the block to slide out of the equipment. After stacking, the storage is completed. The whole process realizes the coordinated processing and efficient storage of different metallurgical wastes.
